SOUND PRODUCING DEVICE Filed Jan. 9, 1928 20' y Z-M M BY WM ATTORNEY Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE GILBERT T. CRAIG, OF LITTLE NECK, NEW YORK, ASSIGNOR TO BAB-ZIM TOY MAFITL FACTURING 00., INQ, OF NEW YORK, N. Y., A CORPORATION OF NEW YORKv SOUND-PRODUCING DEVICE Application filed January 9, 1928. Serial No. 245,361.

This invention relates to improvementsin sound producing devices and has for one of its chief objects the provision of a device of this nature having an air chamber and a vibrator attuned in sympathy with the column of air in the chamber.

Another object of the invention is to provide a device of this nature with a resonator boX divided into different sized chambers 1 each of the said chambers being provided Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and corelation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

' this In the drawings forming a part of specification,

Figure 1 is a front elevation partly in scction of one embodiment of my invention.

Figure 2 is a fragmental sectional view of same taken on line 22 Fig. 1.

Figure 3 is a similar view to Fig. 1, showing a modified form of my invention.

Figure 4 is a sectional view taken on line 44 Fig. 3. Figure 5 is atop plan View of another form of my invention and Figure 6 is an end view of same looking from the right of Fig. 5.

Referring to the drawings in detail and 5 more particularly to Figs. 1 and 2, 10 indicates a resonator box preferably made of 3 seamless metal tubing, and consisting of two chambers, 11 and 12 respectively. The said chambers are each of a diiferentsize lengthwise and are separated by a wall or partition 14 preferably made of cork or like material. The chamber llis provided with a vibrating lip or tongue 15 and the chamber 12 with a tongue 16. These tongues or lips are bent up from the bottom wall 17 of the resonator box (see Fig. 1), the tongue 15 being of a length which when struck for vibrationwill produce a note or tone in harmony or sympathy with the air column in the chamber 11, and the tongue 16 is likewise attuned in sympathy with the air column in the chamber 12. These notes may be alternately struck by grasping the device by the handle 18 and shaking same so that the strikers 19 and 20 which are mounted on the ends of the spring frame 21 will alternately come into striking contact with the tongues 15 and 16 and produce a two tone effect. The frame 21 is preferably made of a single strip of spring sheet metal and is supported in a slot or cut out 22 'in the handle 18 and secured thereto by nails or the like at 23 and 24. The handle 18'is secured to the resonator box by a rod 25 passing through the said handle and the upper and lower walls of the said resonator. The said rod also passes through the partition 14 and holds same in place. One end of the rod 25 is driven into the handle 18 and the opposite end may be riveted into the upper wall of the resonator 10.

In Figs. 3 and 4 I have shown a modified form of my invention in which the resonator comprises a tube or hollow member 30 and provided with a single chamber 31 having a vibrator tongue 32 at each, end thereof, These tongues are attuned to the air column in the chamber 31 and may be alternately struck by striker heads 33 and 34'when the device is operated. "In this instance the striker comprises strikerheads'33. and 34 joined together byv a pin or rod' 35. Pins 36 and 37 projecting from theheads 33 and 34 and almost contacting with the upper wallof the member 30 insure a proper sliding movement of the striker frame from one tongue to the;

other. The handle 18 is in this instance secured'to the lower wall of the tube 30 by means of a rod 38.

In Figs. 5 and 6 the device is in the form of a rattle comprising a resonator box 40 open at one end and provided with a properly tuned vibrator tongue 41 adapted to be struck by a striker head 42 mounted on a spring wire frame-43 secured to ears 44 and 45 of the resonator box 40. The striking head frame 43 is actuated by means of pins 46 and 47 forming a star or ratchet wheel construction which engages the end 48 of the frame 43. The entire rattle is rotatably mounted on a shaft 49 projecting from a handle 50. I11 this instance the device is operated by grasping the handle 50 and swinging the box 40 around the shaft 49.

From the above it will be seen that I have provided a simple and efficient sound producing device that may be utilized as a single or double tone bell like instrument or as a rattle.

Many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof. It is intended that all matters contained herein in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the languageused in the following claims is merely intended to cover all the generic and specific features of the invention herein de scribed, and all statements of the scope of the invention which, as a matter of language,

might be said to fall therebetween, and that materials, sizes and relativities of parts are non-essential, except as called for in the claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A sound producing device, comprising a resonator box, a dividing wall within the box forming a chamber of a predetermined size on each side thereof, a vibrator tongue for each compartment properly tuned thereto, a handle upon which the resonator box is mounted and vibrator tongue strikers resiliently mounted on the handle. I 2. A sound producing device, comprising a resonator box, an air chamber of a predetermined size in the resonator box, a vibrator tongue attuned to the air column in the chamher at one end of the resonator box bent at substantially a right angle to one wall thereof, a" handle upon which the resonator box is mounted, and'a vibrator tongue hammer resiliently mounted on the handle.

' 3. A sound producing device, comprising a resonator box, an air chamber of a predetermined size in the resonator box, a vibrator tongue attuned to the air column in the chamher at one end of the resonator box bent at substantially a right angle to one wall thereof, a handle upon which the resonator box is mounted and a striker for striking the vibrator tongue.

4. In a sound producing device, a hollow resonator box, open at its end, and a vibrator tongue at the said open end, said tongue being attuned tothe air column within the resonator box and bent at substantially a right angle to one wall of said box and integral therewith, the said vibrator tongue being adapted to be struck to produce a musical sound.

In testimony whereof I hereunto aflix my signature.
